Patent GB-101792-A (GB)
Title: Methods of Treating Porous Blocks.
Inventor: FULLER CLAUD EDGAR
IPC: C04B41/47
Filed: 1916-09-12
Abstract: 101,792. Fuller, C. E. Oct. 9, 1915, [Convention date]. Wood, treating with liquids. - Relates to the process for impregnating porous paving blocks by heating them and saturating them with liquid bitumen or asphalt, and consists in cooling them gradually in a separate chamber at atmospheric pressure and at a temperature below the melting point of the bitumen but above the ordinary atmospheric temperature. During the cooling, the exterior coating of bitumen is absorbed into the pores as it contracts. The blocks, stacked on trucks, are first heated in a chamber 8, Fig. 1, and are next run into the saturating-cylinder 1, whence the impregnated blocks are conveyed on rails 7 to the cooling-chamber 9. Part of the track 5 is removable to clear the door 2. The chamber 8 is heated by a burner 69 in a flue 67, Fig. 2, and the chamber 9 is heated partly by a burner 70 in a flue 66 and partly by conduction from the chamber 8. The temperature is controlled by exhausting air from the chambers by a fan 72, and also by dampers 75, 76. The Specification as open to inspection under Sect. 91 (3) (a) comprises also means for heating the saturating-cylinder, and ior supplying and discharging the melted bitumen. The cylinder 1, Fig. 1 (cancelled), is mounted in a furnace 16, over a central lower flue 17 which is heated by a burner 24 and contains baffle members 18; the tank 19 is partly heated by the flue gases which are deflected to the front end by the setting 22 and pass upwards, thence beneath and to the rear of the tank 19 by the setting 23, and again upwards and forwards above the setting 23 to the smoke stack 25. Supplementary burners 26 may be provided. The tank 19 is also heated internally by steam pipes 27 connected to a boiler 31, and the temperatures are indicated by thermometers 34, 35. The blocks having been placed in the cylinder, the air is first exhausted by a pump 41; the melted bitumen is then allowed to flow to the cylinder from the tank by a pipe 36 and branch 37, until the blocks are immersed, and air is then forced into the cylinder by the pump 41 to force the bitumen into the pores. Valves are next opened to allow the bitumen to be forced back to the tank 19 through the pipe 36 and branch 38 by the air pressure, and the blocks are then removed. An indicator 65 operated by a float 63 shows the level of the bitumen in the cylinder. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,157,041. Semi-conductor devices. INTERNATIONAL RECTIFIER CORP. 20 March, 1967 [29 April, 1966], No. 12984/67. Heading H1K. A semi-conductor device, consists of a wafer 11 containing a PN junction and sandwiched between expansion plates 12, 13, e.g. of molybdenum, of which the former is preferably smaller and the latter larger than the wafer, and is held between a housing base 10 forming one terminal and a stud 15 forming another by means of a spring constituted by one or more dished washers 24-26. The washer or washers act between the housing and an annular shoulder 16 on the stud 15. The spring tension depends on the distance between the base and top of the housing and this is adjusted in assembly by inserting shims 43, 44 before welding the body 41 of the housing to its base 10. The housing is assembled by first placing the spring washers in a cup-shaped insulator 40 and fitting this on the stud 15. The housing body 41 is then placed over the stud 15 and the shims 43, 44 are inserted between the body and the base of the housing. The number of shims is adjusted to attain the requisite spring pressure and a weld is then effected between the members 10 and 41.

Patent GB-923179-A (GB)
Title: Process for the production of alkyl tin compounds
IPC: C07F7/22
Filed: 1960-04-20
Abstract: Alkyl-tin compounds are prepared by reacting tin tetrachloride, -bromide or -iodide with alkyl aluminium compounds in the presence of an ether or tertiary amine and in the absence of alkali metal halides.  Tertiary amines specified include triethylamine, tributylamine, dimethylcyclohexylamine and dimethylaniline, as well as heterocyclic bases such as pyridine and quinoline.  Etherates or amine complexes of the alkyl aluminium compounds or of the tin tetrahalide may be used, or the ether may be used as reaction solvent.  It is also possible to carry out the reaction in the absence of an ether or amine and to add the ether or amine in an amount at least equivalent to the aluminium charged.  The reaction product is homogeneous and not a mixture of compounds: its chemical composition is dependent upon the proportions of reagents initially used and on the composition of the aluminium compound.  The alkyl aluminium compound may be a trialkyl aluminium, a dialkyl aluminium chloride, monoalkyl aluminium dichloride or an alkyl aluminium sesquichloride. Specification 768,765 is referred to.

Class 82(2) A machine for washing and drying gear components 48 comprises an endless con- .veyer 11, component carriers 17 spaced apart and secured to the conveyer, an inclined track 22 up which the components are pushed and rotated, pipes 27 and 29 with jets 30 for directing cleaning fluid on to the components, and pipes 34, 35 and 36 with jets 37 for directing air on to the components after cleaning. The inclined endless chain conveyer 11 is driven by a motor 13 and each carrier 17 has opposite parallel arms 18 and stub axles 20 carrying rollers 21. Inclined tracks 22 extend parallel to the conveyer on the outer sides of roller 21 and outer vertical guide plates 23 also extend parallel to the conveyer. Cleaning fluid is supplied to the jets 30 from sump 32b via pump 31, distributing chamber 30b and conduits 30a, the cleaning fluid after washing the components returning to the sump via filter 33c. The cleaning fluid is heated to 140‹F. by electric heater 33 controlled by thermostat 33a. The compressed air supplied to jets 37 and 46a is automatically controlled by means of a pilot valve 42, poppet valve 43 and articulated trip plates 44 which are secured to the conveyer adjacent to the carriers 17. As the tapered end 44a of the trip plate 44 enters between roller 44b and roller 41, the pilot valve 42 is opened to supply compressed air to the jets via line 45, poppet value 43 and conduit 46. With this arrangement compressed air is supplied to the jets only when the carrier is passing below the jets. The rollers 21 of the carrier push the gear components up the inclined track when the elevator is set in motion and the components are rotated during this movement. The track height is adjustable so that the axis of each component is in a plane parallel to the conveyer and passing through the axes of rollers 21.
